IMPROVEMENT IN FOUNTAlN-PENS.

Specification forming part of Letters Patent No. 123,263, dated January30, 187

To all whom it may concern:

Be it known that I, LEVI M. KNISELY, of New Philadelphia, in the countyofTuscara-was and State of Ohio, have invented certain new and usefulImprovements in I ountain-Inkers and Reservoirs for Ink Attached toFountain Pen-Holders; and do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawing and to the letters of reference marked thereon.

The nature of my invention consists in the construction and arrangementofafountain penholder, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, whichforms a part of this specification, and in which Figure l'is alongitudinal vertical section of my entire pen-holder and Fig. 2 is afront view of that part immediately over which the pen is placed.

A represents a small tubular cylinder on which the pen rests, supportedby a shoulder, b, in a larger cylinder, B, thereby preventing the penfrom being pushed too far in. The cylinder A has a small channel, a, atthe lower end on the outside under the pen to conduct the ink from thetube into the pen. This cylinder A is screwed into the tube of a largercylinder, B, about three-quarters of an inch, forming at that end astopper, preventing egress of the ink, except through the tube of thesmall cylinder A, into the channel a, leading it to the pen, said largercylinder B thus becoming afountain or reservoir for ink. The outer endof the cylinder B is provided with an elongated screw-thread, i 011 itsexterior. Upon this end of said cylinder is placed a cylinder, 0, openat one end and closed at the other. .Its interior is provided with ascrew-thread, a to correspond with the screw-thread 3 on the cylinder B,and is of a length equal to the length of the thread of cylinder B, butnot equal to the entire length of the cylinder 0, so that the lattercylinder slides over the former a short distance before the threadsconnect with each other. The cover or rim, being screwed onto thefountain-cylinder, forms an air-chamber, and the screw being turned tothe right, as it were, condenses the air, which, pressing against theink, causes it to flow through the channel of the small cylinder A intothe pen in such quantity only as desired; and, by reversing the motionof the screw to the left, forms a vacuum, creatin g a suction whichcauses the ink to reeede to the fountain until none is left in the pen,and it is there held until the air is again condensed by turning thescrew to the right, as above set forth.

The fountain is filled either by inserting the lower end into a vesselof ink and turnin the screw to the left as often as desired, or bypouring the ink in at the upper end, having first removed the cap orair-chamber, or by taking that offan d pouring intoit, then screwingdown the fountain into the chamber. The pen need not be removed infilling the holder.

To protect the pen, Ilit a cap, D, on its end, and in the end of thiscap is a small orifice, d, to prevent suction when the cap is beingremoved from the holder, thus forming a smooth, complete, cylindrical,capped hydraulic inker and fountain pen-holder, which may be made ofhard rubber or other suitable material, and capable of being carriedabout the person without danger of spilling, and without allowing theink to corrode in the fountain.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The combination of the cylinderA with channel a, the fountain orreservoir B with shoulder b and elongated screw-thread y, thescrew-cover O with screwthread, all constructed and arranged as shownand described, to form a complete hydraulicinker and fountainpen-holder, substantially as herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this15th day of September, 1871.
